The PHU series from GW Instek combines compact design, high performance and maximum flexibility. Thanks to the use of SiC power semiconductors and a multi-range output, the devices are ideal for a wide range of applications - from research to series testing. Thanks to the integrated web server and extensive industrial interfaces, the devices can be easily integrated into laboratory and automation environments.
General features of the series:
- Multi-range output: One power supply unit for numerous current/voltage combinations - saves space and costs.
- Advanced Web Server (AWS): Browser-based operation - no additional software required.
- Adaptive Parallel Connection (APC): Up to 10 devices can be combined - scalable up to 300 kW (depending on model).
- Comprehensive interfaces: LAN, USB (type A/B), EtherCAT, CANopen, Modbus, Profinet, DeviceNet.
- Protection and convenience functions: CV/CC priority, programmable slew rate, bleeder circuit, internal resistance simulation, panel lock.
The PHU 80-340-D model with an output power of 30 kW, a voltage of up to 80 VDC and a maximum current of 340 A is designed for applications with extremely high current requirements at low voltage. It is ideal for high current tests, component characterization and tests in the 48 V system range. Typical areas of application:
- Tests of 48 V battery systems, vehicle electrical systems and electrical loads with high currents
- Simulation of high-current DC loads in the automotive and industrial sectors
- Validation of DC motors, converters and current distributors in the power class up to 340 A
- Power supply of large DC test benches with low voltage
- Integration into automated test systems for control units and power engineering
